{μ-trans-N,N′-Bis[(diphenylphosphanyl)methyl]benzene-1,4-diamine-κ2P:P′}bis{(acetonitrile-κN)[dipyrido[3,2-a:2′,3′-c]phenazine-κ2N4,N5]copper(I)} bis(tetrafluoridoborate)

Abstract

In the centrosymmetric dinuclear title compound, [Cu2(C2H3N)2(C18H10N4)2(C32H30N2P2)](BF4)2, the CuI centre is coordinated by two N atoms from a dipyridophenazine ligand, one P atom from an N,N′-bis[(diphenylphosphanyl)methyl]benzene-1,4-diamine (bpbda) ligand, and one N atom from an acetonitrile molecule in a distorted tetrahedral geometry. The bpbda ligand, lying on an inversion center, bridges two CuI centres into a Z-shaped complex. Intramolecular π–π interactions between the dipyridophenazine ligand and the benzene ring of the bpbda ligand are observed [centroid–centroid distance = 3.459 (3) Å]. The crystal structure also involves intermolecular π–π interactions between the dipyridophenazine ligands [centroid–centroid distance = 3.506 (3) Å], which lead to a one-dimensional supramolecular structure.
